There are well-known differences between various computer brands, and individual PC's generally vary widely. If you need really good agreement, then all the systems need to be viewed under similar light conditions and calibrated (e.g., using a colorimeter, or at least the GretagMacbeth ColorChecker, a printed chart) and you want to generate PDF's with a specific colorspace (not just deviceRGB). For most purposes, it seems to work to use a rough "sRGB" setting where you adjust the monitor (brightness, contrast) to approximate gamma=2.2. Check this with: <http://www.normankoren.com/makingfineprints1A.html#Monitor_test_pattern>. Many LCD's and worn-out CRT's like the ancient NCD on my desk will fail even this simple test. -- George N.
